Figure 13. is a detail perspective view of the connecting deviceillustrated in Figure Figure 1 1 is a detail perspective View of thesocket or, thiinble shown in Figure 12. i

in like oharacters'of reference denote corresponding parts, thereference character '10 indicates a' portion" of the'floor' boards or anautomobile through which projectsthe shank ll of the controllingpedah'for examthe' Clutch release pedal-of the autorno- "jlAe. 1 4 'oThe lock which is adapted to engage around the shank 11 1 as shown in ofthe drawings, comprises a barrel'12 which is provided with'a sightopening 13 and Referring in detail to the drawings wherewhich is:adaptedto receive 'a shank 14, the

latter being preferably cylindrical throughout its length. i

Rotatably mounted upon the shank li is a plurality of tumblers 15. Thesetumblers are each provided with a notch 16 which opens into the bore ofthe tumbler, one end of the notch opening into an annular recess 17.whose walls are beveled as indicated The oppositeends of the walls ofthe notch 16 are also beveled as shown at 18. Extending from the shank ll'ar'e spaced lugs 19 and the corners of these 'lugs'are likewisebeveled as indicated at 20. This permits of the legs readily enteringthe notches 16 when the lugs and notches are in alignment but preventsoperation of the look by .sound and feel. The tumblers are capable ofrotation uponthe shank 14L and 'areheld againstaxial movement in onedirection by means of an annular shoulder 21 arranged within the barrel'12 and'against movement in an opposite direction by means] of a plug 22located within the open end of. the barrel. A

threaded" engagement is provided between the plug 22 and'the barrel 12so that the p g may be c urate y dju ed to Permi of" free, rotation of tt mb filis" With u undue end play. The mblers are pro arrangeddifferently with respect to the numbers or to the divisions between thenumbers, or half numbers so that a wide range of combinations of numbersjmayjbe provided. The plug 22 is held in adjusted position by means of aset screw 27 Whose outer end or head may be riveted so as to" preventits removal. The plug22 is also provided with an axially disposed notch28 for the passage of the lugslS).

Extending'from the outer end' of the plug 22 are spaced arms 29, whilethe shank 14 carriesa transversely disposed arm 30 from dotted-linesinFigure l or the drawings.

Outward movement of the shank 14: is limited by means of a, nut'33 whichis threaded upon the inner end of said shank and which engages thetumblers as shown in Figure 7 of'the drawings... a I

. Secured"within a recess 33 provided in the barrel 12 is a flat bar34:. The opposite edges of this bar are provided with notches 35, thematerialbetweenthese notches defining yieldable'arms 36 which engage thetumblers 23 and hold the latter against accidental movement.

In the operation of the lock, the tumblers are manipulated u'ntiltheproper combination of numbers appears within the sight opening 13, thenumbers 1, 2,3 and 4 appearing in Figure ,8. When, the tumblers areinthis position, the notches 16 will be aligned with the lugs 19 so asto permit the shank ll to be drawn outward as shown in F'gure' 7 of thedrawings-and by the dotted lines in Figure 8. ,The spaced shackles maythus be-engaged around or removed from the shank ofthe pedal and thelock shank 1% moved inwarchwhereupon rotation of the tumblers will lockthe shank in place. Vhen in locked position, thelugs 19 will occupy therecesses 17 of the tumblers. v In the typeset automobiles where thefloor boards are readily removable, there is provided a substantiallyL-shaped arm 37 V which carries at one end a threaded stud 38. vThisstud is engageable in the threadedbore a socket or ,thimble' 39 which'issecured ,to'fan'd extendsthroughthe. floor board 10.

The right angled extension of the L-shaped arm a0 is designed to beplaced against the shank 11 or" the. pedal so that the spaced shackles.-mayibe engaged-around both the .shankand said extension The upperextremity of the extension 40 isprovided with a 'lug 41 so that theshackles are positioned between the arm 37 and the lug 4:1.

The invention is susceptible of various changes inits I"orm,-prop0rtionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within thescope of the appendedclaims.

Having described the invention what is claimed is I 1, Alock comprisinga barrel having a longitudinallyidisposed sight opening therein, ahollow plug secured at one end of the barrel, a longitudinally slidableshank within the barreland extending through the plug, an arm carried bythe plug, an arm carriell by the shank and engageable With the plugcarried arm to provide a shackle and a plu-ralityof indicia carryingtumblers mounted for rotation within the barrel and detachably engagingthe shank to control longitudinal sliding movement of the lat tel; I- 1i '2.
